title: Can patients apply the Ottawa ankle rules to themselves?
abstract: OBJECTIVE
  To determine whether patients with an ankle injury obtained the same results as clinicians when applying the Ottawa ankle rules (a validated clinical decision rule) to themselves.
  
  
  METHODS
  Patients aged >15 years presenting to an inner city emergency department within 48 h of an ankle injury were asked to assess their own injury using the Ottawa ankle rules. The results of their self-assessment were compared with those of a treating clinician.
  
  
  RESULTS
  Poor interobserver agreement was found between patients and clinicians.
  
  
  CONCLUSIONS
  Making the Ottawa ankle rule more widely available to the general public is unlikely to reduce healthcare demand. Indeed, given the apparently low specificity of the rule, demand could actually increase as a result.
